BAND-CUTTER AN D FEEDER FOR TH RASHlNG-MACHINES.

SPECIFICATION forming part of Letters Patent No. 496,764, dated May 2,1893.

Application filed November 3, 1892. Serial No. 450,862- (No model.)

-useful Improvements in Band-Cutters and Feeders for Thrashing-Machines;and I do hereby declare the following to be afull, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same,

reference being had to the accompanying drawings, and to letters ofreference marked thereon, which form a part of this specification.

This invention relates to improvements in band cutters and feeders forthrashing machines.

The object of the inventionis to provide a band cutter and feeder ofimproved construction by means of which the sheaves will be fed beneathband cutting knives and therefrom to the feeding board, said feedingboard having devices for separating the straw and feeding it to thecylinder of the thrasher; and the invention consists in the constructionand combination of the parts, as will be hereinafter fully set forth andparticularly pointed out in the claims.

In the accompanying drawings forming part of this specification: Figure1 is a sectional View of a band cutter and feeder constructed inaccordance with my invention. Fig. 2 is a rear elevation. Fig. 3 is adetail perspective view, partly in section. Fig. 4 is a view of one ofthe agitating fingers detached. Fig. 5 is a detail perspective view,showing the arrangement of the rear set of forks.

The supporting frame of the machine is made up of sect-ions of tubingwhich are coupled to each other by the ordinary pipe couplings as shown.This form of construction provides a cheap and efficient frame, theparts of which can be readily separated when desired.

a a designate parallel bars or tubes, between each pair of which isbolted a block or hearing for a horizontal shaft b, said shaft havingmounted thereon a series of disks B, to which are riveted knives orcutters b-preferably the cutters of a sickle-bar, with serrated edges. Adrive-pulley is keyed on one end of this shaft for rotating the same.

0 designates a short section of a bar or tube which passes throughcouplings attached to the upper ends of the vertical tubes at a and isfurther braced by a rod 0. A bar or tube 0 is attached as shown anddescribed to the upper end of each pair of vertical tubes at a, and atthe outer ends of these horizontal bars or tubes are coupled and bracedupright bars or tubes (1 (1. Near the upper ends of these uprights isattached a crossbar or shaft d upon which are mounted suitable blocks ee having rectangular apertures to receive the upper ends of the forks E.Below the center of these forks and rigidly secu red thereto are blocksf, which are also attached to the bent or crank portions of a horizontalshaft F which is mounted in bearings secured to the uprights (1 d. Atone end of this crank-shaft is a pulley over which passes a belt forrotating the same.

Between the uprights a a'and below the bearings for the shaft 17 arerigidly bolted plates or castings g provided with hooks g which receivestub-shafts attached to and supporting the rear end of the frame of thecarrier belt G.

H designates the front transverse bar or tube of the frame, said barhaving rigidly attached thereto depending blocksh with apertures throughwhich pass the ends of support-' ing arms h attached to the forward orhighest end of the feed-board. The rear or lower end of this feed-boardis provided with a depending apertured block or guide which slides uponan arm 6 secured to the inclined bar or tube I of the frame. Theseguides and arms permit a longitudinal reciprocation of the feed-board,such a movement being imparted by a pitman-rod K, one end of which issuitably connected to the feed-board while the other end is attached toa crank-shaft journaled in bearings depending from the bars or tubes I;a pulley being keyed on one end of the shaft over which a belt passesfor rotating the shaft.

L L designate agitating fingers, which are bent as shown in Fig. 4, theportion Z of each being located in apertures in the cross-piece j orsteps located between the upper and lower sections of the feed-board,while the crankshaped ends are located beneath the feedboard and areconnected to each other by a bar L'. When this bar is reciprocated thefingers L will be shifted from side to side to agitate or separate thestraw. The movement of this bar is attained by means of flexibleconnections which are attached to each end of the bar and pass aroundguide pulleys to a stationary part of the frame where they are secured;one of said flexible connections being attached to the frame in front ofthe bar L while the other is attached to the frame in V the rear of saidbar, so that when the feedboard is reciprocated the flexible connectionswill be alternately drawn upon to actuate the agitating fingers.

M M designate the rear forks, which are attached to the crank-portions mof the shaft m, the upper ends of said forks being guided in blocksmounted on a cross-bar or shaft secured in a slot in the upper end ofthe standard N, said cross-bar or shaft being adj ustable to and fromthe crank-shaft so that the throw of the forks can be varied. The framecarrying the rear forks can be readily removed when these forks are notneeded.

In the operation the sheaves are fed to the carrier belt and are movedunder the knives by the forks E so as to out the bands, after which theyfall upon the upper section of the feed-board and move downward betweenthe oscillating fingers L which separate the straw so that it will beloosely fed to the cylinder of the thrashing machine, the movement ofthe straw beyond the fingers being caused by the vibration of thefeeding-board assisted by the forks M.

The feeding devicehereinbefore described is simple and is not liable toget out of order, and it will be noted that the vibration of thefeeding-board imparts an oscillating movement to the agitating fingers.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In a band cutter and feeder for thrashing machines, the combinationof a shaft carrying a transverse series of disks or plates between eachpair of which are secured sickleteeth and an endless carrier locatedbeneath the same, substantially as shown, and for the purpose set forth.

2. In a band cutter and feeder for thrashing machines, the combinationof aband outter, a reciprocating feeding-board, separating or agitatingfingers journaled so as to pass through the feeding-board, the ends ofthe fingers being connected to a bar, and flexible connections passingover guide pulleys carried by the feeding board, the flexibleconnections being attached to the frame for reciprocating the bar so asto impart an oscillating movement to the fingers, substantially asshown, and for the purpose set forth.

3. In a feeder for thrashing machines, the combination of an inclinedfeeding-table suitably supported and provided with means for imparting areciprocating motion thereto, fingers L journaled in a step or cross-barforming a part of the feeding-table, the ends of the fingers below thefeed table being bent to form crank portions which are connected to a 1transverse bar, flexible connections suitably the bar attached to thefingers will be actuated, substantially as shown and'set forth.

the guide pulleys, substantially as shown, and

for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.
